Tacrolimus, Sirolimus and Methotrexate as Graft Versus Host Disease Prophylaxis After Blood Stem Cell Transplantation
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this study is to determine if the incidence of Graft vs. Host Disease (GVHD) after non-myeloablative transplantation can be reduced by using a combination of three immune suppressive medication; sirolimus, tacrolimus and methotrexate.
Patients will be admitted to the hospital and receive chemotherapy and stem cell transplant(SCT). The total duration of hospitalization for the procedure is approximately 8 days. Once admitted the patient will receive fludarabine daily for 4 days, busulfex once daily for 4 days. Two days after chemotherapy has ended, the patient will receive the infusion of donor cells.
Just prior to the transplant and following the transplant, patients will receive sirolimus (orally), tacrolimus (orally) and low doses of methotrexate (chemotherapy). Methotrexate will be given on days 1,3 and 6 after transplant.
Sirolimus will be tapered beginning week 9 after transplant if there is no evidence of GVHD and will be eliminated on week 26 if clinically feasible.
Tacrolimus will be tapered beginning week 9 after transplant if there is no evidence of GVHD and will be eliminated on week 26 if clinically feasible.
Patients will also receive medication to help prevent possible infection.
After stem cell infusion, patients will be examined and have blood tests weekly for 1 month. At the 1 month visit, a bone marrow biopsy will performed looking for evidence of donor cells in the bone marrow. After the one month evaluation the patient will be examined every 2 weeks and a repeat bone marrow performed 3-4 months after transplant.
